Yushi Sanxian (Pinyin dié shī sān xián) is a plucked stringed musical instrument of the Yi people. Unique shape, round tone, for solo, ensemble or folk song and dance accompaniment. It is popular in the areas of Honghe, Yuanyang and Lvchun in Honghe Hani and Yi Autonomous Prefecture of Yunnan Province, especially in Lushi Township, Honghe County, hence the name.

It consists of a resonance tube, headstock, piano rods, pegs, bridges and strings, etc. The total length of the piano body is about 85 cm.

During traditional ethnic festivals such as Torch Festival and Flower Arranging Festival, the Yi people wear festive costumes and gather together to sing, dance and dance to the fullest.
